The London Times 1858

I can imagine a poor mother in the west of Ireland … sitting on the furthest crag that juts into the Atlantic, no longer contemplating that waste of water as a desolate wilderness which separates her from those she loves, but as a means of instant communication with them “

Cardinal Wiseman, Catholic primate of England, in his speech honouring Charles Bright, chief engineer, at Dublin’s Mansion House, 1858
